SPECIFICATION forming part Of Letters Patent NQ. 520,923, dated June 5,1894.'.

Application filed December 4,1893. Serial No.492,705. (No model.)

To @ZZ whom it may con/cern:

I e it known 'that I, JOHN ILLINGWORTH, a cltizen of the United States,residing at Newark, 1n the county of Essex and State of New Jersey, haveinvented cert-ain new and useful Improvements in Ingot-Molds; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled inthe art to whichit appertalns to make and use the same, refer.- ence vbeing had to theaccompanying drawings, and to letters of reference marked there- Vandcombinations of parts, all substantially as will be hereinafter setforth and finally embraced in the clauses of the claims.

0 Referring to the accompanying drawings, 1n which like letters indicatecorresponding parts in each of the views, Figure l is a plan and Fig. 2aside elevation of the improved machine, and Figs. 3, 4, 5, 6 and 7 aredetail views illustrating the construction of the sections of thematrix, Fig. 3 being a horizontal section of one of the upper sections,Fig. 4 a

section of the outer casing thereof, Fig. 5 a back view of an innermember of one of the sections, Fig. 6 a section thereof, and Fig. 7 ahorizontal section of the lower sections.

In said drawings, a, indicates the frame of the machine providing asupporting arm, b, or bearings for the matrix sections and for certainhydraulic cylinders, c and cl, all substantially as illustrated in' thepatent above referred to. The matrix sections are horizontally separableto allow the ingot to gravitate automatically, vwhen opened, from thechamber therein. The sections c and f, are fixed in vertical line, oneabove the other, upon the frame or bed, ct, of the machine by bolts orother suitable means admitting of removal, and the sections g, 7L,corresponding `therewith are in connection vwith the hydraulic pistonsc', d', ot the cylinders c and CZ, and are thus movable to and from thefixed sections, e, f, under the powery exerted by said pistons. Thehydraulic cylinders are provided with ducts and valves, in any usualarrangement, by which the water is brought to' press the piston back orforth as may be required. The matrix sections are each provided withwater jackets by which the molten metal is cooled more or less rapidly,the said jackets being also provided-with pipes `vor ducts, by which thewarm water is removed from and cold water conveyed to the chambersaround said matrix sections.

In the construction embraced in my former patent, the lower chamber wassomewhat larger than the upper chamber formed between the sections, andthe lower chamber served merely as a cooling chamber and not, in anysense, as a matrix or mold chamber, it being larger, than the upperchamber horizontally so that the ingot gravitated therethrough withoutobstruction and thus the lower sections were not necessarily separable.

In my improved construction, thelower sections are separable and are,preferably, smaller in the diameter in the line of separation, so that,when the ingot, formed in the upper chamber,is lowered intothelowerchamber and the movable lower section is forced to its closedposition, there will not only be a direct contact of the said sectionswith the semi-hardened ingot, but also a compression serving, inconnection with the other features Vof the invention,in preventing anytendency to pipe. Theactual contact of the separable, lower, waterjacketed sections serves to facilitate the cooling of the ingot.

The sections e, f, and g, h, are each V-shaped in cross section and soavoid wall lines in the matrix parallel with the line of separationtending to bind the metal in the chamber, as will be understood. Y,

The water j acketed sections are furthermore, of peculiar constructionin that the parts are interchangeable, andare strengthened to enablethem to compress the ingot as hereinafter more fully described.

The peculiarities of construction are illustrated more clearly in thedetail figures, Figs.

3 to 7, wherel indicates an outer casing, which is open at one side toreceive the matrix portion and at the opposite ends is provided withrecesses m, into which the end ribs of the said matrix portion, n, areclosely titted so as to make impervious joints, or joints sufficientlyimpervious for the purpose. Said matrix portion, n, has the V-shapedpart, o, in which the ingot is formed and at the back is longitudinallyribbed, as at p, at the longitudinal angle. It is also provided withlongitudinal iianges p', at the opposite longitudinal edges, which areformed to engage corresponding Bauges, Z', on the casing. T0 strengthenthe matrix portion still further, whereby they are better fitted toresist the compressing operation effectively, it is provided with aseries of transverse ribs, q, of which the end ribs t the recesses in asabove described and the intermediate ribs bear against the inner wall ofthe casing. The said intermediate ribs are arched as shown clearly inFigs. 6 and 7. The arch being integral with said V-shaped portion at theedges and at the intermediate angle. Openings, r, are formed under thearches between them and the oppositely inclined sides of the V- shapedportion, which allow a free iiow of cooling liquid therethrough.

The matrix portions of the lower sections f and 7i, are formed in theingot chamber, t, as shown in Fig. 7, where the angles are shown to becored out or cut away, as at u, u, so that there will be no bearing ofthe cooling surfaces upon the corners of the ingot. Thus said cornersare not cooled with undue rapidity. The ingot is broken, as it islowered from time to time, by the hydraulic cylinder and piston c, w, inthe manner described heretofore.

In operating the invention, the parts being as shown in Fig. 2, theingot, A, where it projects below the arm, b, is broken or severed bymeans of the hydraulic piston, a charge of liquid metal having beenpoured in at the top of the mold to replace that lowered in the mold inbringing the downwardly projecting ingot portion to the position shown.The pistons c', CZ', aie next drawn back with their sections g and h,the mold or matrix chambers, t, being thus opened so that the ingot isagain allowed to gravitate, the gravitation being free and quick becauseof the peculiar relation of the mold walls to the ingot. The downwardmovement of the ingot being stopped by the iioor or bearing B, the moldor matrix sections are again closed together, the metal is poured againand the operations repeated. When the poured metal cools suftciently tosustain itself, and is lowered into the lower chamber, the action of thesections f, h, is to rapidly cool the ingot and to coinpress the samethus avoiding the tendency of the metal to pipe to a large extent asabove indicated.

Having thus described the invention, what I claim as new is l. In aningot mold or matrix, the mold or matrix section consisting of the outercase and an inner matrix portion consisting of a V-sliaped part providedwith a longitudinal rib at the back angle and transverse ribs,substantially as set forth. n

2. In an ingot machine the combination with the bed or frame having asupport for the mold sections, of said sections, t-he sections g, h, ofwhich are separable from the sections c, f, said sections forming moldor matrix chambers, t, the upper one of which is larger than the lowerone, and the lower seetions serving to compress the ingot substan tiallyas set forth.

3. In an ingot machine, the combination with the frame or bed, the armb, cylinders c, d, piston rods c', d', and severing device, of separablemold or matrix sections, the lower ones of which are recessed at theangles, as at u, substantially as and for the purposes set forth.

4t. In an ingot machine, the mold section comprising a casing, l, and aseparable matrix portion having the V-shaped part, o, and at the back ofsaid V-shaped part, the ribs, q, the intermediate ribs being arched overthe back walls of said V-shaped portion, and being integral with saidV-shaped portions at the back angle and near the edges, an opening r,being formed admitting a free flow of cooling liquid therethrough,substantially as set forth.

5. In an ingot machine, the combination with the casing open at one sideto receive the matrix portion, and at the ends to receive end ribs, ofsaid matrix portion V-shaped in plan and having said end ribs, andhaving intermediate arches which serve to strengthen the V-shapedportion and are open to allow a iiow of liquid therethrough,substantially as set forth.

6. The combination with the casings of an ingot machine of matrixportions which are Vshaped in plan and have on the insides at thelongitudinal angles thereof, ribs, p, and at various points in theirlengths having transverse arches, q, serving to strengthen said V-shapedmatrix portions, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this25th day of November, 1893.

JOHN ILLINGWORTH.
